Regarding Gerry Anderson's 'UFO' series. I've just tracked down and watched the first two episodes on YouTube. I'd forgotten how sexist it was. And I'm beginning to think that Anderson must have got all his funding from the tobacco industry, as everyone is smoking all the time.

Actually, Terry Pratchett's Discworld was animated by Cosgrove Hall, who also had their hand in other Doctor Who projects, including an online story called Scream of the Shalka. Here's the title sequence, albeit just before a few minutes of story.

The alien or the animation? Keep in mind that it was designed for streaming over a website. Similar animation was used for an animated David Tennant story, The Infinite Quest, and the animated versions of missing episodes 1 and 4 of The Invasion.

Yes, that's Richard E Grant playing the Doctor. This series was commissioned for the BBC website when it seemed unlikely that any new episodes would get made. Unfortunately, shortly before showing Scream of the Shalka, it was announced that the new series would be made.
